BACKGROUND

1. Field of Invention

The present invention relates to an electronic system. More particularly, the present invention relates to an electronic system with a mobile device and an expansion device.

2. Description of Related Art

There has been a strong need for a mobile device such as a cell phone or a PDA to be small enough to carry along easily and at the same time be powerful enough for experiencing similar look-and-feel (for example, large LCD) and complex functions as those on a laptop or PC. However, it is easily seen that these two requirements conflict. The shrinking of the size of the mobile devices makes it hard to implement a large display panel and a circuit board providing complex functions. So far, there is no satisfying form factor announced by any handset manufacturer yet.

Accordingly, what is needed is an electronic system to provide the convenience, large display panel and complex functions at the same time to overcome the above issues. The present invention addresses such a need.

SUMMARY

An electronic system is provided. The electronic system comprises: a processor, a mobile device, a plurality of expansion ports and an expansion device. The mobile device can work as a standalone system, wherein the mobile device comprises a plurality of first function modules. The expansion device comprises a plurality of second function modules, wherein the expansion device connects to the mobile device through the plurality of expansion ports. When the mobile device and the expansion device are connected together to form the electronic system, the processor controls the electronic system to perform the function of the plurality of first and second function modules.

It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the invention as claimed.

The mobile device 11 has its own processor and its own input interface to deal with its own function modules, e.g. a cell phone, a PDA or other mobile devices. The mobile device 11 comprises a plurality of first function modules (not shown). The expansion device 13 comprises a plurality of second function modules (not shown), wherein the expansion device 13 connects to the mobile device 11 through the plurality of expansion ports 12. When the mobile device 11 and the expansion device 13 are connected together to form the electronic system 1, the processor 10 controls the electronic system 1 to perform the function of the plurality of first and second function modules.

In a second embodiment as depicted in FIG. 1B, the processor 10 can be in the expansion device 13. When the processor 10 is in the expansion device 13, the processor in the mobile device 11 acts as a secondary processor 110. The processor 10 in the expansion device 13 substantially controls the electronic system 1. The expansion device 13 can be a standalone system such as a PC or a notebook computer to adapt the mobile device 11 as a wireless communication device of the PC or the notebook computer.

FIG. 2A shows another block diagram of the electronic system 1. The plurality of first function modules of the mobile device 11 comprise a first display screen 111, the plurality of expansion ports 12 comprise a display expansion port 121, and the plurality of second function modules of the expansion device 13 comprise a second display screen 131 connected to the mobile device 11 through the display expansion port 121. The second display screen 131 has a larger display area than the first display screen 111. When the mobile device 11 and the expansion device 13 are connected together, the electronic system 1 shows the information of the electronic system 1 on the second display screen 131. In other words, a user can use the first display screen 111 when the system is the standalone mobile device 11 for convenience or use the second display screen 131 when the system is the electronic system I for larger display screen. Further, both the mobile device 11 and the expansion device 13 can have at least one input interface. FIG. 2B shows an embodiment of the electronic system 1 with a keypad 11′ and a keypad 13′ on the mobile device 11 and on the expansion device 13 respectively.

FIG. 3A shows another block diagram of the electronic system 1. The plurality of first function modules of the mobile device 11 comprise a first battery module 112, the plurality of expansion ports 12 comprise a battery expansion port 122, and the plurality of second function modules of the expansion device 13 comprise a second battery module 132 connected to the mobile device 11 through the display expansion port 122. When the mobile device 11 and the expansion device 13 are connected together, both the first and the second battery modules 112, 132 provide the power of the electronic system 1. In the present embodiment, the plurality of first function modules further comprise a charging circuit 112′ to connect to an external power source (not shown) and the first battery module 112 to charge the first battery module 112 directly and charge the second battery module 132 through the battery expansion port 122. In other embodiment, as depicted in FIG. 3B, the charging circuit 132′ is in the expansion device 13 to charge the second battery module 132 directly and charge the first battery module 112 through the battery expansion port 122.

The first antenna is adapted to the wireless technology such as: GSM, GPRS, EDGE, WCDMA, HSDPA, HSUPA, HSPA+, LTE, WiMax, WiFi, Bluetooth and GPS. The second antenna is adapted to the wireless technology such as: GPS, DVB-T and DVB-H.

FIG. 5 shows another block diagram of the electronic system 1. The plurality of first function modules of the mobile device 11 comprise a USB port 114. There are two major types of USB port: (1) A USB port acts as a client for data transfer or power charging and (2) A USB port supports On-the-go technology and acts as a host for data transfer. The type and the number of the USB port can be easily modified by people who skilled in the art. The plurality of second function modules of the expansion device 13 also comprises a USB port 134 as described above, and the type and the number of the USB port on the expansion device 13 can also be easily modified by people who skilled in the art.

FIG. 6A shows a perspective view of the electronic system 1 of the present invention. The plurality of expansion ports 12 are formed on a sidewall 60 of the expansion device 13 to make the mobile device 11 connect to the expansion device 13. FIG. 6B is another perspective view of the electronic system 1 of the present invention. A chamfer 61 is formed on the expansion device 13, wherein the plurality of expansion ports 12 are formed in the chamfer the mobile devices is adapted to the chamfer 61 and connects to the expansion device 13. The chamfer 61 can be formed in one corner of the expansion device 13 as depicted in FIG. 6B, or in the middle part of the expansion device 13 as depicted in FIG. 6C.
